Lets not pretend short sellers arent willing to exaggerate their case against in order to make a quick buck. They are talking their book afterall. I would say whining is a sign of weakness more than dishonesty.
Sure. Both management and short sellers are. But structurally, the table is tilted in favor of management.
The problem are never short-sellers per se, bur rather the fabrications some diseminate to induce panics. Those guys that try to manipulate the market with false information should be vilified, not short sellers in general.
That rarely happens, in reality. It's just the boogey-man CEOs tell their investors at night so they can blame someone for bad stock performance.
There are strict rules against market manipulation and short sellers are under very large amounts of scrutiny. It's not uncommon for legitimate short sellers to get pressured/investigated by SEC/equivalents. (see Wirecard and BaFin)
Furthermore it's absolutely possible and in many circumstances likely that the price of a put decreases even if the underlying stock's price decreases, for example if the volatility also decreases.
I don't think many informed individuals treat shorting stock the same way they treat buying puts nor do they attempt to accomplish the same purpose.
